IPC: B60T8/66
Filed: 1993-03-09
Abstract: PURPOSE:To provide an anti-lock control device which restrains frequent change of control modes due to fluctuations in the detected value of ground vehicle velocity by determining a control mode of braking pressure according to the relation between ground vehicle velocity detected by a Doppler type ground vehicle velocity sensor and an actual wheel velocity, so that the control mode is changed in such a manner as to have a hysteresis as to changes in the relation. CONSTITUTION:A ground vehicle velocity VGS is detected by a ground vehicle velocity sensor and a controller calculates a target wheel velocity VR based on the ground vehicle velocity VGS, and determines a control mode of braking pressure according to the relatioship between the target wheel velocity VR and an actual wheel velocity VW detected by a wheel velocity sensor. Dead zones (set as VRH and VRL) are set as to the target wheel velocity VR, and as long as the actual vehicle velocity VW is within the dead zones, change of the braking pressure control mode is inhibited.
